▎ 摘　　要

NOVELTY - Anisotropic silicon carbide conductive ceramic comprises 90.5-96.4 wt.% silicon carbide (SiC) matrix, and 2-8 wt.% graphene nanosheets and balance is sintering aid dispersed in matrix. USE - Anisotropic silicon carbide conductive ceramic used in the field of electronic components, electrical switches, sensors and displays (claimed), and used for wearable series conductive ceramics, electrocardiogram (ECG) conductive ceramics, charging PIN, wire-cut conductive columns, anti-static conductive ceramics, and wave absorbing materials. ADVANTAGE - The anisotropic silicon carbide conductive ceramic has improved conductivity and anisotropy of electrical property by introducing graphene nano-sheet. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing anisotropic silicon carbide conductive ceramic, which involves: (a) weighing and adding silicon carbide powder, boron carbide and carbon powder into graphene dispersion, and mixing to obtain mixed slurry; (b) drying and sieving or spraying and granulating mixed slurry to obtain mixed powder; and (c) performing discharge plasma sintering to obtained mixed powder to obtain anisotropic silicon carbide conductive ceramic.
